Comparison of Outcomes between Percutaneous and Surgical Placement of Peritoneal Dialysis Catheters in Uremic Patients: A Meta-Analysis

Abstract

<b><i>Background:</i></b> The optimal technique for inserting peritoneal dialysis catheters in uremic patients remains debated. This meta-analysis aimed to summarize the current evidence evaluating the efficacy and safety of percutaneous insertion methods compared to surgical methods. <b><i>Method:</i></b> A literature search was performed in the PubMed, EMBASE, Cochrane, and Web of Science databases. The primary outcome was defined as catheter survival. The secondary outcomes were mechanical and infectious complications related to catheter insertion. <b><i>Results:</i></b> Twenty studies were finally identified, including 2 randomized controlled trials. The pooled results of catheter survival, overall mechanical complications, and infectious complications were not significant (odds ratio [OR] = 1.10, 95% confidence interval (CI) = 0.76–1.57, <i>p</i> = 0.62; OR = 0.73, 95% CI = 0.48–1.11, <i>p</i> = 0.14; and OR = 0.64, 95% CI = 0.37–1.09, <i>p</i> = 0.14, respectively). Comparison stratified by the blind percutaneous method versus open surgery indicated a lower overall number of mechanical complications (OR = 0.54, 95% CI = 0.31–0.93, <i>I</i>² = 72%) and malposition rate (OR = 0.56, 95% CI = 0.34–0.90, <i>I</i>² = 0%). The leakage rate was higher in the blind percutaneous group than in the open surgery group (OR = 2.55, 95% CI = 1.72–3.79, <i>I</i>² = 0%); the guided percutaneous method achieved a similar leakage risk to the surgical methods. <b><i>Conclusions:</i></b> The blind percutaneous method performed better with fewer overall mechanical complications and less malposition than open surgery. The leakage risk was higher in the blind percutaneous group, while the guided percutaneous placement group showed similar outcomes to the surgical method groups. Percutaneous methods also had a lower infection risk, which needs further evidence to be confirmed.
